| OBJECTIVE:To explore cardiac reserve function of normal pregnant women and pregnant women with hypertensive disorders complicating pregnancy.METHODS:Five hundred and eighty-two healthy non-pregnant women and healthy pregnant women,twenty gestational hypertension pregnant women, twenty-six mild preeclampsia pregnant women ,twenty-three severe preeclampsia pregnant women were voluntarily involved in this study.Based on the digital technique of heart sound signal processing, the heart rate(HR), the ratio of the amplitude of the first heart sound to the amplitude of the second heart sound (S1/S2) and the ratio of diastolic to systolic duration (D/S) of non-pregnant women , healthy pregnancy women and hypertensive disorders complicating pregnancy pregnant women were measured,calculated,and analyzed by the Sport Cardiac Contractility Monitor. The prognosis of the neonatal and parturient were followed up.RESULTS: A small correlation was found among HR, D/S and gestational weeks,whereas there was no significant correlation between S1/S2 and gestational weeks. HR, S1/S2 and D/S were found significant differences when compared among the different groups (non-pregnant women vs pregnant women (28-36weeks group, 37-40weeks group), normal pregnant women vs preeclampsia (mild, severe)). Everybody in non-pregnant women group was found D/S≧1.30. 64.33% of pregnant women(28-36weeks group, 37-40weeks group) were found 1.005.00, D/S<1.00). Four cases of newborns in preeclampsia group died in neonatal ICU.CONCLUSIONS: With the increase of the gestational weeks, the cardiac reserve function of the pregnant women decreased. The increases of the incidence of cesarean section and bad results of the neonatal and parturient were correlated to decreased cardiac reserve function in preeclampsia women. Non-invasive test of the cardiac reserve function for the pregnant women, especially for preeclampsia women, could be widely used clinically.
